5. The Doctor, The Widow And The Wardrobe (2011 Christmas Special)
Christmas is a time of joy and goodwill and, for Doctor Who fans, the arrival of another Christmas Special. But this one just wasn't worth the wait. In fact, despite its timey-wimey take on Narnia's The Lion, The Witch & The Wardrobe, this episode contained nothing significant in any way, shape or form. What's more, it gave the Doctor an 'immune' threat by featuring creatures made of wood and Amy and Rory's absence made the whole affair a pretty boring indeed.
